eigthy one plus a number
The square root of 81 is: ±9 (9 or -9)A square root is a number which, when multiplied by itself, equals the original number. As 9 x 9 = 81 and -9 x -9 = 81, the answer is plus or minus nine.
The number that is being modified (8 in the following model) is referred to as the base number, or simply, base. Base Number----> 81 <------ Exponent
Without an equality sign and not knowing the plus or minus value of 81 it can't be solved. If you mean: z+81 = 9z-7 Then: z-9z = -7-81 => -8z = -88 By dividing both sides by -8: z = 11
3^(-2x + 2) = 81? log(3^(-2x + 2)) = log(81) (-2x+2)log(3) = log(81) -2x = log(81)/log(3) - 2 x = (-1/2)(log(81)/log(3)) + 1
It is 256.
log37 - log3x = 4 log3(7/x) = 4 7/x = 34 = 81 x = 7/81
No it is not. The log of any number, with the same number as the base, is always 1.
Well, isn't that just a happy little math question! When you see "log base 81 of 9," you're looking for the power you need to raise 81 to get 9. Since 81 to the power of 1/2 equals 9, the answer is 1/2. Just a little mathematical magic to brighten your day!
log9(x)=2 x=9^2 x=81
log3(x)=4 x=3^4 x=81

The above question rewritten as an equation:81/100=0.95d or to put all the numbers in similar terms:.81=.95dIn order to solve for d, remember the logarithm definition: logax=N means that aN=xTherefore,log.9(.81)=5dSince logs are base 10, you need to change to base .9, to solve the left side of the equation:log10(.81)/log10(.9)=2Therefore: 2=5d or d=2/5 or 0.4
78 + 79 + 80 + 80 + 81 + 81 = 479
I guess you mean the value of the power of 3 is at most 1000, not the value of 3^3, 3^4, ..., 3^1000 Logarithms tell you the power to which the base must be raised to get the number. eg for common logs (logs base 10) lg 100 = 2 since 10^2 = 100. To find the largest power of 3 which is at most 1000, the logs to base 3 or 1000 needs to be taken; if the result is not a whole number, the decimal portion is ignored (ie the number is truncated) and only the whole number is considered. [In the following log_3 means logs to base 3, and log is the log to any base, often common logs (lg) or natural logs (ln = logs to base e) are used (for the whole calculation).] log_3(1000) = log(1000)/log(3) ≈ 6.3 → highest power of 3 less than or equal to 1000 is 6, ie 3^6. Thus the powers of 3 in the range 3-1000 are: 3^1 = 3 3^2 = 9 3^3 = 27 3^4 = 81 3^5 = 243 3^6 = 729
81*82/2= 3321
