let's set up an equation:
x-4=9
solve normally:
x=13
the answer would be4.7^-10^4
Answer:
πr²= 12.56
r²=12.56/3.14 = 4
r= 2
therefore , diameter = 2r = 2×2= 4 mm
Answer:
yes the answer is never true
Step-by-step explanation:
as the correct answer is

This is an EXPONENT.
To do this all we need to do is multiply the base by itself how many times the power says.
(-6)² = (-6) × (-6) = 36
Recall that any negative number times another negative number is positive so that is why this would be positive.
So, (-6)² = 36
