7x = 5
x log(7) = log(5)
x = log(5) / (log(7) = 0.82709 (rounded)
5 and 3/7
To convert 1.8 to a fraction, we can rewrite it as 18/10. Simplifying this fraction gives us 9/5. To convert 9/5 to a decimal, we divide the numerator (9) by the denominator (5), which equals 1.8.
( 5 ) ( x ) = 60x = ( 60 ) / ( 5 ) = 12
1.6 = one and three fifths
it equals 1/25, or 0.04. A number to a negative power is the reciprocal of the number to that same positive power. x^(-y) = 1/(x^y)
Negative 5 to the second power would be -5 times -5 which would be 25.
It would be rewritten as y=(2/5)x+3
A = 5 + 3*b To solve for b, rewrite as b = (A - 5) / 3
4(x + y - 5) = 0
5 to the third power equals 125
== == y = -x + 5
59 / 56 = 59-6 = 53 That is not written as a power of 5 i.e. (x5) You have to rewrite 53 to x5 = 2.6265278...5
-5
To find what power of 3 equals 243, you can express 243 as a power of 3. Since (3^5 = 243), it follows that 3 to the power of 5 equals 243. Therefore, the answer is (3^5 = 243).
10 to the 5th power
9x = 243 ln(9x) = ln(243) xln(9) = ln(243) x = ln(243)/ln(9) x = 2.5 NB this works with log10 too. NBB if you don't have a calculator, this kinda question will only have easy values of x like integer values or 0.5, so its always worth chucking numbers in.
