2*5=10
Write the base as many times as the power indicates.2³ would be 2 · 2 · 2.5² would be 5 · 5.
2*5^2 ^2 here means the same as a 2 in superscript, or "squared".
Two (2). 3^5 5^3
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.
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
2 times 3 times 5
2 times 5 times 7 times x times y
5 goes in to 2 0.4 times
It is: 2 times 3^2 times 5 = 90 no indices are needed for 2 and 5
It is: 2^1 times 3^2 times 5^2 = 450
