2*5^2 ^2 here means the same as a 2 in superscript, or "squared".
answer: 90 ^ 9x10 ^ ^ 3x3x5x2 2 2 exponet is 3x 5
3^2 x 5
Answer: Exponents are numbers that are multiplied by itself that. Example: 2 to the power of 2( 22) means: 2 x 2,which equals 4. ( the exponet of 2 is squared-you call it squared ONLY if the original number has the exponet of 2...and an exponet of 3 is cubed.like 23) or 9 to the power of 5 (or 9 with an exponet of 5, means:95 or 9x 9 x 9x 9x 9,(five 9's.)which equals=59,049. NOT to be confused with 9 x 5,which equals= 45. (See the difference? You can use your scientific calculator to check it!) So , you name your exponet by writing the number to be exponeted ,like number 9 in the example above, with a smaller 5 above and to the right of the original 9,that small number IS the EXPONET.So 9 with an exponet of 5the smaller number to the right is 5 and it IS the EXPONET and is ,written 95 .
2*5=10
2 x 5 x 5 is the prime factorization of 50.
To write the expression (2 \times 2 \times 3 \times 3 \times 5 \times 5) using indices, you group the identical factors together. This gives you (2^2 \times 3^2 \times 5^2). Each base number is raised to the power of the number of times it appears in the product.
4 with a 5 as its exponet
To write the expression for double 2 and then add 5, you first calculate double 2, which is (2 \times 2 = 4). Then, you add 5 to this result: (4 + 5). The complete expression is ( (2 \times 2) + 5 ), which simplifies to 9.
(2 x 5)2
Write the base as many times as the power indicates.2³ would be 2 · 2 · 2.5² would be 5 · 5.
2 times 3 times 5
2 times 5 times 7 times x times y
