<span>The exponent of a number says how many times to use the number in a multiplication.</span><span>In 82 the "2" says to use 8 twice in a multiplication,
so 82 = 8 × 8 = 64
</span><span>In words: 82 could be called "8 to the power 2" or "8 to the second power", or simply "8 squared"</span>
Answer:
x = 2√2
Step-by-step explanation:
This is a 45-45-90 triangle. This means that if the legs are x, then the hypotenuse is x√2.
In the case, the hypotenuse is already 4. So we have the equation:
x√2 = 4
Multiply both sides by √2
2x = 4√2
Divide both sides by 2
x = 2√2
