Because it can't be expressed as a fraction
The square root of (any number that isn't a perfect square) is irrational.
No because the square root of 900 is 30 which is a rational number
The expression "30 to the square root" is not clearly defined, but if you mean (30^{\sqrt{30}}), then this expression is irrational because it involves raising a rational number (30) to an irrational exponent ((\sqrt{30})). In general, a rational number raised to an irrational power results in an irrational number. Hence, (30^{\sqrt{30}}) is irrational.
No. The square root of 900 is 30, which is most definitely a rational number.
real numbers, irrational numbers, ...
10 times pi, 24 times the square root of 2, plenty more (infinitely more).
The square root of 32 approximates to 5.66
Yes; the square root of 900 is 30 which is a rational number.
No.
It is 30
Square them both, find a non-square integer between those two results, and then take the square root of that number. In other words, find a non-square integer between 25 and 49, and since there is only one square number between them, 36, that should be easy; let's pick 42, and then take the square root of it. Ta da! √42 is an irrational number between 5 and 7, its first 30 digits being 6.48074069840786023096596743608.
The square root of 900 is 30. This is because the square root of a number is a value that, when multiplied by itself, gives the original number. In this case, 30 multiplied by 30 equals 900.
