The expression 7^n/7^5 simplifies to 7^p. If n = 18, what is the value of the exponent p? Show your work and explain how you fou

nirvana33 [79]

When you divide two powers of the same base, you subtract the exponents:

$\dfrac{a^b}{a^c} = a^{b-c}$

This means that, in your case,

$\dfrac{7^n}{7^5} = 7^p \iff 7^{n-5} = 7^p \iff n-5 = p$

So, if $n=18$ , the equation becomes

$18-5 = p \iff p = 13$

Write an expression used to find 4x275 using mental math and properties of numbers

elena-s [515]

What I suggest is to round the numbers. 4 rounds up to 5. 275 would round up to 280 or 300 whatever is easier. your expression would be 5*280 or 5*300.
I hope this helped :)
