Question

Why is 10'15 equal to 10'11? explain ur thinking. ___ 10'4

Answer 1

`(10^(15))/(10^4)=10^(11)\text{ for the following reasons:}`
`To\text{ calcultate }(10^(15))/(10^4)\text{ you would have to apply exponent rule}`

Exponent rule is the following:

`(x^a)/(x^b)=x^(a-b)`
`\text{Therefore, if for }(10^(15))/(10^4)\text{ a is 15 and b is 4, therefore:}`
`(10^(15))/(10^4)=10^(15-4)`
`So,\text{ }10^{\mleft\{15-4\mright\}}=10^(11)`
