x+2 = log4(40)

4 ^(x+2) = 40 (x+2)log4 = log(4x10) (x+2)log4 = log4 + log10 (x+2)log4 = log4 + 1 (x+2)log4 - log4 =1 (x+2-1)log4 = 1 X = 1/log4 - 1

চীন আরো আগে ২০২০ সালের করোনার মধ্যে নিজে থেকেই এই প্রস্তাব দিয়েছিলো

when x=5 then x^3-x^2=5^3-5^2=100.

Very bad way to solve it

❤❤ thanks 😊😊👍🏻👍🏻

7^(ln(70)/(ln(7) = 70

❤❤ tank you 🤩🤩

instead of doing all those steps you could immediately change it into log base 4 of 40 and get the answer

your calculation is so simple;We can find a lot way for solving this proublem

But why came the x down to the base?

nice, good work, I like more final answer x= log (8)24 its like more compact
