Answer:
78
Step-by-step explanation:
6(2x² - 5) = [?] if x = -3
6(2(-3)² - 5)
6(2(9) - 5)
6(18 - 5)
6(13) = 78

Answer:
2×12^(1/4)
Step-by-step explanation:
Step 1: Express 192 as a multiple of primes:
192=2×2×2×2×2×2×3= 2^4 × 2^2 × 3
Step 2: We can take the fourth root of 2^4 and get 2 but we cannot take the fourth root of 2^2 or 3.
Step 3: Now we have 2 × fourth root of 2^2 ×3 = 2 × 12^(1/4)
Answer:-3
Step-by-step explanation:
know
a+b=1
a-b=2
by combine the equatio you will get 2a+b-b=3
the b cancal each other out left 2a=3 and 3/2 = 1.5 for a
so if 1.5=a then apply 1.5 into a+b=1 and a-b=2 you will receive -.5 for b and 1.5/-.5 will equal to -3
