could someone help me with math?

Question

Find this product. Enter your answer in scientific notation.

(1.3×10^5)(2.7×10^7)

Answer 1

Hi Seth,

 

When you multiply numbers in scientific notation, you multiply the numbers with decimals and you add the exponents.

 

So, 1.3 x 2.7 = 3.51

 

The exponents add up to 12

 

I'll let you now write it in scientific notation.

 

Have fun.

Answer 2

You can find the value here by multiplying the coefficients (1.3×2.7=3.51) and adding the exponents (5+7=12).

Meaning that the end product of (1.3×105) and (2.7×107) is 3.51×10^12.
