How is multiplying exponents (x² ⋅ x⁴) different from raising a power to a power ((x²)⁴)?
goblinko [34]

Answer:

When you are "multiplying" exponents, you're really just adding them together. So in the case of (x² ⋅ x⁴), you add the exponents:

2 + 4 = 6

x^{6} would be the answer.

On the other hand, raising a power to a power, is actually multiplying them. So it would just be:

2 ⋅ 4 = 8

x^{8} would be the answer.

Divide x to the 1 half power divided by x to the 2 sevenths power.
juin [17]

\frac{x^\frac{1}{2} }{x^\frac{2}{7}}

According to the rule of exponents \frac{a^m}{a^n} = a^{(m-n)} , i.e. when two terms are in division with same base , we subtract the exponents

So

\frac{x^\frac{1}{2} }{x^\frac{2}{7}} = x^{(\frac{1}{2}) - (\frac{2}{7})}

=x^\frac{3}{14}

Or

x to the 3 fourteenths power
