The numbers are: (-14 +sq rt 190) and (-14 -sq rt 190) Check: (-14 +sq rt 190)+(-14 -sq rt 190) = -28 and (-14 +sq rt 190)*(-14 -sq rt 190) = 6
The numbers are: -2 +2*sq rt 19 and -2 -2*sq rt 19 Check: (-2 +2*sq rt 19)*(-2 -2*sq rt 19) = -72 and (-2 +2*sq rt 19)+(-2 -2*sq rt 19) = -4
I use the symbol ^ to mean 'to the power of' 144^(-1/2) = 1/144^(1/2) = 1/sq rt( 144) = ±1/12
there are 144 Sq. in. in 1 sq. foot. Therefore you divide sq. in. by 144 = sq. ft. or sq.in./144=sq.ft.
-454
It is: cos(15) = (sq rt of 6+sq rt of 2)/4
sq rt of 81 is 9 sq rt of 100 is 10 sq rt of 83 is between 9 and 10 and thus is not an integer/ counting number
Length of the diagonal = sq rt (10002mm2 + 7502mm2) = sq rt (1000000mm2 + 562500mm2) = sq rt (1562500mm2) = 1250mm
2 sq ft = 2*144 = 288 sq inches.2 sq ft = 2*144 = 288 sq inches.2 sq ft = 2*144 = 288 sq inches.2 sq ft = 2*144 = 288 sq inches.
The numbers are -9-sq rt of 41 and -9+sq rt of 41
