Answer» 1} √7/72} [√7+√6]/133} [√5-√2]/74} [√7+2]/9Step-by-step explanation: 1} 1/√7 = (1/√7) × (-√7/-√7) = -√7/(√7×-√7) = -√7/-7 = √7/7 2} 1/(√7-√6) = 1/(√7-√6)×[(√7+√6)/(√7+√6)] = [√7+√6]/[(√7×√7)-(√6×-√6)] = [√7+√6]/7+6 = [√7+√6]/13 3} 1/(√5+√2) = [1/(√5+√2)]×[(√5-√2)/(√5-√2)] = [√5-√2]/[(√5×√5) - (√2×-√2)] = [√5-√2]/[5+2] = [√5-√2]/74} 1/(√7-2) = [1/(√7-2)]×[(√7+2)/(√7+2)] = [√7+2]/[(√7×√7) - (-2×2)] = [√7+2]/7+2 = [√7+2]/9 |
