Question

Simplify the expression write the expression in scientific notation (5 times 10^7) (6 times 10^4)

Answer 1

5 times 10^7= 50000000

6 times 10^4= 60000

(50000000)(60000)

Answer
3000000000000

Answer 2

You can multiply the coefficients and powers separately:

$(5 \times 10^7) \times (6 \times 10^4) = (5 \times 6) \times (10^7 \times 10^4)$

Solve the first set of parentheses:

$5 \times 6 = 30$

Solve the second set of parentheses:

$10^7 \times 10^4 = 10^{7+4} = 10^{11}$

Now the expression can be written as follows:

$30 \times 10^{11}$

You can divide 30 by 10, so you can add one to the power for 10^11 and get your answer:

$30 \times 10^{11} = \boxed{3 \times 10^{12}}$
