Choose the correct simplification of the expression a to the 7th power times b to the 8th power all over a to the 4th power time s b to the 4th power
2 answers:
The simplification of the expression will be as follows: (a^7b^8)/(a^4b^4) According to the rules of indices, when you divide numbers with the same base, it's the same as subtracting their powers. Hence we shall have: (a^7b^8)/(a^4b^4) =(a^(7-4))(b^(8-4)) =a^3b^4 the answer is a^3b^4
Answer:
just took the exam it is a^3b^4

Answer:
<h3>Given</h3>
m∠REG = 78° mAR = 46° ER ≅ GA <h3>Solution</h3>
m∠GAR = 180° - m∠REG = 180° - 78° = 102° (supplementary angles sum to 180°) m∠TAR = 1/2mAR = 1/2(46°) = 23° (tangent chord angle is half the size of intercepted arc) m∠GAN = 180° - (m∠TAR + m∠GAR) = 180° - (23° + 102°) = 55° (straight angle is 180°) mAG = 2m∠GAN = 2(55°) = 110° mRE = mAG = 110° (as ER ≅ GA) mGE = 360° - (mAG + mAR + mRE) = 360° - (110° + 46° + 110°) = 94° (full circle is 360°)
