If the ellipse x2a2−7+y213−5a=1 is inscribed in a square of side length √2a, then a is equal to
Verify the following :
(i) 37×(56+1213)=(37×56)+(37×1213) (ii) −154×(37+−125)=(−154×37)+(−154×−125) (iii) (−83+−1312)×56=(−83×56)+(−1312×56) (iv) −167×(−89+−76)=(−167×−89)+(−167×−76)
State, true or false : (i) 79=7+59+5(ii) 79=7−59−5(iii) 79=7×59×5(iv) 79=7÷59÷5(v) −5−12is a negative rational number(vi) −1325is smaller than −2513.
