A. 0.64
B. 1.2
C. 12
D. 0.064
How do you simplify this?
can any one help please?
0.4 ³ = ( 4 / 10 ) ³ = 4 ³ / 10 ³ = 64 / 1000 = 0.064
To simplify the expression (0.4)^3, you need to raise 0.4 to the power of 3.
Raising a number to a power means multiplying it by itself the number of times indicated by the exponent. In this case, we need to multiply 0.4 by itself three times.
So, (0.4)^3 = 0.4 * 0.4 * 0.4 = 0.064
Therefore, the simplified expression is 0.064.
Choosing the correct answer, D, 0.064, simplifies the expression correctly.
To simplify the expression (0.4)^3, you need to raise 0.4 to the power of 3.
(0.4)^3 = 0.4 x 0.4 x 0.4
Calculating this, we get:
(0.4)^3 = 0.064
Therefore, the simplified expression is 0.064.
So, the correct answer is D. 0.064.
