Question

write the following in exponential form

{a} product of 4 cubed and 5 squared
{b}sum of 7 raised to the power of 4 and 9 raised to the power 5.

Answer 1

a. 89 is the first answer

Answer 2

Answer:

a) $4^3\times 5^2=1\times 10^4 +6 \times 10^3+0\times 10^2+0\times 10^1$

b) $7^4+9^5=6\times 10^5+1\times 10^4 +4\times 10^3+5\times 10^2+0\times 10^1$

Step-by-step explanation:

Given : {a} product of 4 cubed and 5 squared

{b}sum of 7 raised to the power of 4 and 9 raised to the power 5.

To Write in exponential form :

{a} product of 4 cubed and 5 squared  = $4^3\times 5^2$

First we solve this expression

$4^3\times 5^2$

$=64\times 25$

$=1600$

In exponential form - $1\times 10^4 +6 \times 10^3+0\times 10^2+0\times 10^1$

{b} sum of 7 raised to the power of 4 and 9 raised to the power 5 = $7^4+9^5$

First we solve this expression

$7^4+9^5$

$=2401\times 59049$

$=61450$

In exponential form - $6\times 10^5+1\times 10^4 +4\times 10^3+5\times 10^2+0\times 10^1$
