8^2 = 64 since 8*8 = 64
Squaring a number is the same as multiplying it by itself.
Since 8^2 = 64, this means
1/64 = 1/(8^2) = 8^(-2)
So, 1/64 = 8^(-2)
where the exponent is negative 2
Answer:
SSS
Step-by-step explanation:
We can see that 2 sides are equal already, and because they share a side, that side is also equal. So, side side side.
Answer: -5x+3x²+5
Step-by-step explanation:
(-2x+4x²+5)-(x²+3x)
=-2x+4x²+5-x²-3x
=-2x-3x+4x²-x²+5
=-5x+3x²+5
=3x²-5x+5 (if you are required to write in standard form)
500-100=400
5(400)=2000
399+10=409
2000+409+2409
5(2409)=12045
3(12045)-36135
so in total it's equal to 36135
Answer:
x = 68/33
