Question

9. find the simplified form of the expression
(8 × 10^7)(7 × 10^4)

Answer 1

(8*10^(7))(7*10^(4))

Raising a number to the 7th power is the same as multiplying the number by itself 7 times. In this case, 10 raised to the 7th power is 10000000.
(8*10000000)(7*10^(4))

Multiply 8 by 10000000 to get 80000000.
(80000000)(7*10^(4))

Raising a number to the 4th power is the same as multiplying the number by itself 4 times. In this case, 10 raised to the 4th power is 10000.
(80000000)(7*10000)

Multiply 7 by 10000 to get 70000.
(80000000)(70000)

Multiply 80000000 by 70000 to get 5600000000000.
(5600000000000)
