Answer:
No he is not correct. As the answer would be -2/5 = -0.4 and 5/-2 = -2.5 as the answer is also not opposite.
Let us take each number as x = 2x , 3x, 4x
(2x)³+(3x)³+(4x)³=12375
8x³+27x³+64x³=12375
99x³=12375
x³=12375/99
=125
x =∛125
x=5
2x=2×5=10
3x=3×5=15
4x=4×5=20
therefore, the three numbers are 10,15 and 20 .....
Hope it helps !!
Answer:
z/y
Step-by-step explanation:
when dividing with exponents, you simply subtract the variables w exponents
y^5 - y^6 = y^-1 (which is equal to 1/y)
z^3 - z^2 = z^1 (which is equal to z/1)
1/y * z/1 = z/y
