So first you plug 6 into the equation which is 4(6)-10.
Using PEMDAS, you solve what’s in the parenthesis first and you get 24-10.
24-10=14
f(6)=14
(8*4*2/8*7)^2 x (8^0/7^-3)^3 x 7^-9
Simplify the equations:
(8*4*2/8*7)^2 = (64/56)^2 = (8/7)^2
(8^0/7^-3)^3 = (1/7^-3)^3 = 7^9
Now you have :
(8/7)^2 x 7^9 x 7^-9
Multiply 7^9 x 7^-9 by adding the exponents to get 7^0, which = 1
Now you have:
(8/7)^2 x 1
(8/7)^2 = (8x8) / (7x7) = 64/49
64/49 x 1 = 64/49
Answer:
366.
-1493.
Step-by-step explanation:
54.8-6.9-12
You perform the multiplications first:
= 432 - 54 - 12
= 378 - 12
= 366.
5-2.83.9-4
= 5 - 166* 9 - 4
= 5 - 1494 - 4
= -1489 - 4
= -1493
