sqr7 + sqr7
= 2sqr7
= about 5.29, rounded off to 2 decimal places
You might have been tempted to write sqr(7+sqr7) but PEMDAS, arithmetic order of operations, requires exponents before addition, E before A
and sqr7 = 7^(1/2) so square root comes before addition. square root is a type of exponent. roots are fractional exponents.
sqr(7+sqr7) = about 3.11
