how do i solve 46.2x10-2
Hi, Vanessa! All you'll need to do to find your answer is move the decimal point two places to the left because the exponent is 2 and it is negative. If you move the decimal point two places to the left, you arrive at the answer: .462. If the exponent was a positive 2, you would have moved the decimal point two places to the right to arrive at the correct answer.
Hi Vanessa,
46.2 x 10-2 = 46.2 ÷ 100 = 0.462
This is because negative exponents show that that term in the expression is really under the division bar.
So, 10-2 really means 1 / 102 or 1/100 or ÷ 100
When we divide by 100, the decimal point moves two places to the left in the number.
