can anyone help me on this? please
(2x)^3 + 2^3x
2x^3 = 8x^3
2^3x = 8x
8x^3+8x
or if you prefer,
8x(x^2+1)
Of course, I can help you with this. To simplify the expression (2x)^3 + 2^3x, we can apply the rules of exponents.
First, let's simplify (2x)^3. To raise a power to a power, we multiply the exponents. In this case, the exponent of (2x)^3 is 3, so we can rewrite it as (2x)(2x)(2x).
When we multiply these three terms together, we multiply the coefficients (2 * 2 * 2) and multiply the variables (x * x * x). This gives us 8x^3.
Next, let's simplify 2^3x. To raise a base to a power, we multiply the exponents. In this case, the base is 2 and the exponent is 3x.
Multiplying these together gives us (2^3)(2^x) = 8 * 2^x.
Now, we can rewrite the original expression as 8x^3 + 8 * 2^x.
Therefore, the simplified expression is 8x^3 + 8 * 2^x.
