x=\log_421-\log_44\\
x=\log_4\dfrac{21}{4}\\
x=\dfrac{\ln \dfrac{21}{4}}{\ln 4}\approx 1.1962

Simplify the following expression<br>6a^4c+8ac^2-4a^4c-15-10ac^2
aleksandr82 [10.1K]

Answer:

2a^4c-2ac^2-15

Step-by-step explanation:

Sorry, I not sure if this is right or not cause I don't know if the exponent for -4a^4c is that or -4a^4c-15, but I'm just going to go with -4a^4c. However aside from that you just combine like terms.
