Hello, I have a quick question. What is the answer to 46.2*10^-2? I think its 4620. is that not right?
Another question is what is the answer to 2x^2+3cy-4y^2? X=2 and Y=-4 they say that the answer is 32. I think they are wrong. Please help.
+4473 46.2*10^-2 --> You have to move the decimal place to the left twice (since it is ^-2) instead of right twice, so the answer will be 0.462.
2x^2+3cy-4y^2; x = 2 & y = -4
2(2^2) + 3c(-4) - 4(-4^2) -->
8 -12c - 64 -->
We need to know: c = ?
