Does anyone know this?

( 11 + 4) ÷ 3 × √64

oh i used an algebra helper, i searched on go ogle and got 40

40

Step-by-step explanation:

Following the order of operations you need to do the parenthases first and 11+4 is 15. Then you divide that by 3 which is 5. Then you are going to need to multiply 5 × √64 which the square root of 64 is 8 so you multiply 5 × 8 which is 40.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
