Question

How to write an expression equivalent to b11 over b4 in the form b?

Answer 1

$\dfrac{b^{11}}{b^4} = b^{11-4} = b^7$

Answer 2

The equivalence of the given expression is $b^7$

Laws of indices

Given the indices expression

$\frac{b^{11}}{b^4}$

From the given indices, you can see that the bases are the same. Using the division law of indices, we will have:

$\frac{b^{11}}{b^4} = b^{11-4} = b^7$

Hence the equivalence of the given expression is $b^7$
