Question

find a simplified form of the expression. give your answer in scientific notation 

(3 x 10^8)x(9x10^7)

shinalcantara · Answer

you just have to multiply the bases.
3 x 9 = ?
add the exponents of the base 10
10^8(10^7)= 10^(8+7)

anonymous · Answer

thats it ?

shinalcantara · Answer

You will have it as
$$27 \times 10^{15}$$
But since you are to have it in scientific notation and the rule to expressing numbers in scientific notation states that the factor to be multiplied by 10^n is more than or equal to 1 but less than 10. Then you'll have it as
$$2.7 \times 10^{16}$$
