Question

I can not figure out the answer to this problem. (^6)(-7^6+5) I'm not sure if that sign is correct. It's suppose to be the symbol that looks like a check mark and goes over the 6 on left and over the 6+5 on right. Please help

Answer 1

Is this the sign? (√)

If so, this means square root of whatever follows.

I hope this helps.

Answer 2

We use the ^ symbol for exponents and sqrt( ) or sqt( )for the square root of something. So do most computerized math sites and programs such as Google and Excel, where the available symbols are limited.

sqrt(6)*(-7sqrt(6)+5)
= -7*6 + 5 srt(6)
= 5 sqrt(6) -42
